AOD-9604 UK — hGH Fragment 176-191 Research Guide
Also known as hGH fragment 176-191
AOD-9604 is a synthetic fragment of human growth hormone corresponding to residues 176–191, the C-terminal region of the molecule. It is studied specifically because it isolates part of the growth hormone sequence without carrying the full hormone's activity.
This page explains what the fragment is, what the published research covers, and the two-stage reconstitution AOD-9604 requires.
For in vitro research use only — not for human or animal consumption. Not a licensed medicine in the UK. Nothing on this page is medical advice.
What is AOD-9604?
Growth hormone is a 191-amino-acid protein. AOD-9604 reproduces only the final 16 residues, with a tyrosine added for stability. That fragment is associated in research with lipid metabolism but does not act on the growth hormone receptor in the way the intact hormone does.
Because it is a fragment rather than a secretagogue, AOD-9604 does not stimulate endogenous growth hormone release — which is what distinguishes it from Ipamorelin, CJC-1295 or Tesamorelin.
What the published research reports
Preclinical work has examined the fragment's association with lipolysis and adipose tissue metabolism, and human trial data exists from earlier development programmes. Results across studies are mixed and it is not a licensed medicine in the UK.
It is supplied strictly for in vitro research use only. Nothing here is medical advice.

Is AOD-9604 the same as growth hormone?
No. It reproduces only residues 176–191 of the 191-amino-acid growth hormone sequence and does not act as full growth hormone or as a secretagogue.
Is AOD-9604 legal in the UK?
AOD-9604 is legal to buy and possess in the UK for laboratory research purposes. It is not a licensed medicine in the UK, is not prescribed by the NHS, and is supplied strictly for in vitro research use only — not for human or animal consumption.
How is AOD-9604 reconstituted?
AOD-9604 is supplied as a sealed lyophilised vial. We do not provide preparation or usage guidance; it is sold for in vitro research use only.
Do you supply a Certificate of Analysis for AOD-9604?
Yes. Our batches are independently HPLC and mass-spec tested and the batch number on the vial matches a published Certificate of Analysis, so purity can be verified before use.
